Former reality star Josh Duggar called himself the "biggest hypocrite ever" and revealed he had "been unfaithful" to his wife in a public statement after his name was linked in news reports to a data breach of the Ashley Madison adultery website.

"I am so ashamed of the double life that I have been living and am grieved for the hurt, pain and disgrace my sin has caused my wife and family," Duggar, 27, said in a statement, which was posted on his parents' blog.

His parents, Jim Bob and Michelle, said their hearts were broken by the news.

"When we learned of this late last night our hearts were broken," they said. "As we continue to place our trust in God we ask for your prayers for Josh, Anna, our grandchildren and our entire family."

Josh Duggar said he also became addicted to watching pornography and said he was "a bad example."

In May, he admitted he had "acted inexcusably" amid allegations that he fondled young girls, including his sister, as a teenager. The statement came after In Touch Weekly uncovered a police report that said he had been interviewed in 2006 about sexual abuse accusations from a few years earlier.

The revelations led to the cancellation of the family's reality show, "19 Kids and Counting," which aired on TLC. Duggar also resigned his position as a lobbyist at the conservative Family Research Council.
